Title: Procédé et appareil de retransmission dans un système de communication sans fil à relais
Inventor: CHANG YOUNG-BIN
IPC: H04B17/40
Filed: 2007-05-29
Abstract: L'invention concerne un appareil et un procédé permettant d'effectuer une demande de retransmission automatique (ARQ) dans un système de communication sans fil à relais. Le procédé consiste à effectuer une ARQ avec la station de base (BS), à transmettre des données reçues avec succès de la BS à une station mobile (MS) et à retransmettre des données correspondantes à la MS, lorsqu'un message d'indication de retransmission est reçu de la BS. Etant donné que la station relais (RS) ne retransmet que les données exemptes d'erreurs au récepteur, la fiabilité des données reçues au niveau du récepteur peut être améliorée. La charge appliquée à la RS peut être réduite car l'émetteur commande la demande de retransmission automatique.
